Join a facebook group and annoy my girlfriend?

My girlfriend has a horse (a traditional cob) called Harry who she's about to start entering for shows. As a joke, a while ago I created a facebook profile for Harry which I periodically update the status on, to muse on life from Harry's perspective: complaining about her putting a rug on me when it's warm, musing over the quality of hay, extolling the virtues of hay, saying how great it is being in a field, and posting bad horse-related puns like "Horses live in a stable home", "Horses are the worst nay-sayers", "Horses are like passion: best when unbridled" that sort of thing. Aweful, I know.

My girlfriend is going to trim the fuzzy hair (aka: the beard), which I think makes him look cool, from Harry's chin this afternoon and I've set up a facebook group (as Harry) protesting.

What I thought would be funny is if next time she checks there are lots of people she doesn't know signed up to the group "Save Harry's Beard!".

You won't get spammed or anything and you can leave after a couple of days, I just want to see her face this evening when she clocks the group and it's got 20+ members. I will not be sending out friend requests or anything like that, this is purely to get a giggle and a look of disapproval from my girlfriend. For some reason I like it when she says "Why am I going out with you again?"

If this sort of (odd) self-promotion is not allowed then I'm sorry and I won't do it again!

Moreso, an innocent HORSE'S BEARD! Oh the horse-manity!!!
Edit: I am member #7, BTW.
SHAVE *****S, NOT HORSES!!!
Edit 2: I just decided to start growing my beard out a few days ago- coincidence?I think not!

Thanks so much for getting into the spirit of my stupid request. Zoe saw the page, saw it had 41 members and was totally bemused! She read through all the comments you left and thought they were brilliant. So thanks very much.

Oh, and as for Harry... the clippers broke, so if there's a God up there, he'd definitely be a member of the group!
